now all that's left to do is shade in the top of the eye, finish the hair, erase guidelines, and all the other stuff necessary. then u can shade ^^ what I always do for shading is choose a light source, then shade the stuff farther away from the light source darker. for example, the light source is the tip-left for this one. i also like to do the shiny thing for the hair.
remember there's no one way of drawing people, hair, eyes, etc. form your own style, this is just a help for the basic idea ^^
be sure to comment and rate and stuff ^^
